Description
The present invention relates to a kind of fuel oil emulsifier, particularly relate to a kind of fuel oil emulsifier of direct water mixing.
In the prior art, notification number is to disclose a kind of water-diesel blend machine emulsifier unit in the Chinese patent of CN2049683U, this emulsifier unit is that the water coolant in the Water Jacket is directly introduced in the fine cleaner and the diesel oil mixing and emulsifying through unidirectional adjustable throttling by cleaning strainer, its weak point is: (1) is because fuel oil is to carry out in fine cleaner with mixing of water, its mixing effect is very poor, and the filtration of process fine cleaner, also can cause separating of fuel oil and water, therefore be difficult to reach complete emulsification; (2) oil return of this device remains and gets back to Oil Tank, can't guarantee the water mixing constant rate, also can cause Oil Tank ponding simultaneously and influences diesel engine works better running.
The fuel oil emulsifier that the purpose of this invention is to provide a kind of directly water mixing and emulsify well.
The objective of the invention is to realize by following technical measures: it comprises Oil Tank, gear low-pressure delivery pump, safe spill valve, fine cleaner, injection pump, oil thrower and water supply installation, it is characterized in that: described fine cleaner is installed in before the gear low-pressure delivery pump, water source in the described water supply installation is introduced gear low-pressure delivery pump from water tank by the throttling variable valve, safe spill valve is arranged on the relief outlet of gear low-pressure delivery pump, be drilled with drainback passage on the pump housing of described toothed gear pump, the used oil pipe of described injection pump and oil thrower all leads to the oil-in of gear low-pressure delivery pump, and is returned in the toothed gear pump by this oil-in.
Throttling variable valve in the water supply installation of the present invention can be used to control the water mixing ratio; The ideal range of water mixing weight percent is 10～25%, and wherein optimum value is 13%, and the water that is mixed is ordinary tap water, without any need for additive; Fine cleaner can be avoided being separated by fine cleaner after water and the oil mixing before being installed in gear low-pressure delivery pump again; The design of the drainback passage on the gear low-pressure delivery pump pump housing can be guaranteed the water mixing constant rate, and a large amount of mixing oils is returned in the gear low-pressure delivery pump with the shortest oil return path, to be increased in the stirring number of times in the toothed gear pump.
Described in the present invention gear low-pressure delivery pump should satisfy big discharge capacity and high-revolving requirement, wherein, discharge capacity is 6 times of maximum oil consumption, minimum speed is 1500 rev/mins, can mix at short notice to impel fuel oil and water.
Fuel oil among the present invention can be diesel oil or heavy oil.
As a further improvement on the present invention, can a pressure charging valve be installed between the relief outlet of described gear low-pressure delivery pump and spill valve, its internal diameter is half of toothed gear pump oil outlet internal diameter, and its inner chamber is provided with the rifle groove, make mixing oil in the shape of a spiral direction discharge forward, quicken to stir.
Should try one's best near injection pump in the installation site of the gear low-pressure delivery pump described in the present invention, its height should be lower than injection pump, with the long-pending oil of minimizing system.The position of described Oil Tank and water tank should be higher than the position of purifier separately, so as can be automatically the air in the removal system apace.
As a further improvement on the present invention; the position of the turnover oil pipe of described injection pump is at the position on the lower side of high-pressure pump grease chamber; can make the moisture that to separate after the unexpected shutdown can flow back to drainback passage on the gear low-pressure delivery pump automatically like this; make it begin to stir again, to guarantee startability once starting.When routine operation, should before shutdown, about half an hour water be closed, intrasystem moisture is burnt substantially, thereby guaranteed the smooth of startup once more.
As a further improvement on the present invention, also can set up magnetic valve in the described water supply installation, it be shut down promptly have a power failure and close water valve automatically, forget when preventing to shut down to guarantee startability by shutoff valve.
Water supply installation of the present invention is introduced gear low-pressure delivery pump through the throttling variable valve with water, fueller is introduced gear low-pressure delivery pump from Oil Tank through fine cleaner with fuel oil, oil and water carry out mixing the first time in gear low-pressure delivery pump, and only need just can be uniformly mixed into both peach liquid in about one minute; Entering the pressure charging valve that inner chamber is provided with the rifle groove by the relief outlet of low pressure gear pump subsequently carries out mixing the second time, at this moment, toothed gear pump need certain pressure could be constantly promptly with oil and water in the shape of a spiral direction push away, in pipeline, carry out further thorough mixing; Entering spill valve subsequently again mixes for the third time, promptly utilize the spill valve spring with the passage of oil stream become having many bends or curves, cut apart mutually, increase greatly and stir number of times, a large amount of unnecessary fuel oils are then got back in the toothed gear pump by spill valve set drainback passage on gear low-pressure delivery pump and are stirred repeatedly; Mixing for the 4th time is to utilize injection pump to stir, and after mixing oil entered high-pressure oil chamber, because plunger upward and downward, the convex part of plunger beat up and down, and upwards extruding of plunger, downward decimate action make peach liquid become oyster white; When the plunger squeeze pressure reached the pressure that overcomes the delivery valve spring, above-mentioned oyster white mixing oil was divided into four parts and enters high-pressure line and carry out again very fierce extruding and stir; When the pressure of high pressure mixing oil surpasses the spring force of oil thrower, will extrude aperture and be atomized into the vaporific cylinder that enters at a high speed, at this moment, the mixing oil that enters cylinder is various water-in-oil particulates, when they run in the cylinder 400～600 ℃ high temperature suddenly, take place sharply to expand and explode, thereby mist of oil is further resolved into more tiny particulate, simultaneously because blast also can make oil mix more evenly with pressurized air, therefore, it is more complete to burn, the discharge capacity of black smoke reduces, and oil consumption also decreases; When above-mentioned fine particles is sprayed on the metallic surface of combustion chamber, original carbon deposit shake pine can be stripped down flue side by side.
The present invention compared with prior art has following advantage: (1) since the present invention the fine cleaner in the prime the fuel system is placed before the gear low-pressure delivery pump, and on the pump housing of gear low-pressure delivery pump, drainback passage is set, both can guarantee the water mixing constant rate, water and oil are mixed in prime the fuel system fast repeatedly, make oil in water emulsion by oneself continuously, therefore, not only economy but also can reduce and pollute 80% was saved fuel oil 10～20%.(2) recondition expense of the present invention is low, easy to operate, safe and reliable.(3) of the present invention of many uses, both can be used for the prime the fuel system of diesel engine, also can be used for Industrial Boiler, cooking oil oven etc.(4) because the present invention can remove carbon deposit, therefore can improve the lubricating quality of machine oil, reduce the wearing and tearing of diesel engine, prolong the life-span of diesel engine, reduce maintenance cost.(5) because the position of the turnover oil pipe of injection pump of the present invention at the position on the lower side of high-pressure pump grease chamber, can prevent prime the fuel system ponding, make it have reliable startability.
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of embodiments of the invention.
